Shining a new light on the LCD experience


At Corning, we envision a display-driven future. And reliable 5G - and even 6G - signal is core to how those displays bring entertainment and connection to people everywhere. Our Optical Communications division is hard at work making 5G a reality far and wide. And Corning Display is ready to assist. Here's how:

As 5G signal reaches farther, the next priority will be ensuring that signal remains strong as it reaches its final destination. Even the strongest 5G signals are easily disrupted by physical barriers. For example, buildings can create signal dead zones outdoors and walls and furniture can create dead zones indoors. These disruptions limit signal coverage and would often require an additional network of signal repeaters.

A reconfigurable intelligent surface (RIS) integrates with small cells to help deliver more seamless 5G coverage. Inside the RIS, the right substrate - with the right properties and patterning - plays a key role.

Together with our innovation partners, Corning determined that a glass substrate with low dielectric loss is ideal, ensuring the 5G signal maintains its strength as it meets with - and is reflected by - the RIS. Precise conducting patterning is added to this specialized glass before it's added to either a passive or active RIS device.

While 5G signal extension may seem like a departure from the TVs and tablets that are often the focus in the display industry, enabling RIS technology is one of many adjacent opportunities industry leaders are exploring. Materials science expertise led Corning and our innovation partners to transform the TV landscape over the last 50 years, and we are applying that same expertise to explore glass-based solutions to new opportunities every day.
